Does this work properly with IOS 6 and the iPad2 and, if not, will Apple pay for the return shipping of a defective product?

I would like to purchase the AV Adapter if it works as it is described...mirroring everything on your iPad 2. However, I read MANY complaints about the cable not working with IOS 6 and that the adapter is not working with all of the apps. I read that the adapter only relays sound/audio on some apps, while not rendering video. These reviews are on the Apple website. So, before purchasing, I would appreciate confirmation that the adapter works as advertised and, if not, and the adapter is, in fact, defective, that Apple would pay for the return shipping.
